Syria war has displaced 7 million Syrians, or one-third of population, UN refugee agency says

DAMASCUS, Syria – The head of the U.N. refugee agency in Syria says 7 million Syrians, or almost one-third of the population, have been displaced by the country's civil war.

Tarik Kurdi told The Associated Press on Monday that 5 million of the displaced are still in Syria while about 2 million have fled to neighboring countries. He says 2 million children are among those directly affected by the war.

Kurdi says U.N. assistance has been a "drop in the sea of humanitarian need" and that the funding gap is "very, very wide." He says international donors have sent less than one-third of the money needed to help those displaced by the war.

More than 100,000 Syrians have been killed since an uprising against Syrian President Bashar Assad erupted in 2011.
